The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The automatic locking apparatus of protective cover for diagonal saw comprises holder 1 and sliding seat 2.
Described holder 1 is fixedly installed on framework 5, and it is substantially perpendicular with the side of framework 5.As preferably, described holder 1 is one-body molded with framework 5.
Sliding seat 2 is rotationally connected with holder 1.As preferably, described sliding seat 2 is threaded with holder 1 by bolt 3, and described bolt 3 is substantially parallel with the side of framework 5.Sliding seat 2 can be rotated for rotating shaft by bolt 3 relatively.Establish back-moving spring 4 in described sliding seat 2; Described back-moving spring 4 is sheathed on the bolt 3 as rotating shaft; And back-moving spring 4 one ends are fixedly installed on holder 1, and the other end is fixedly installed on sliding seat 2.Be fixedly installed plectrum 2a and catch 2b on described sliding seat 2.Described catch 2b stretches into framework 5 edges and movable shield 6 is locked when not working.Described catch 2b is substantially vertical with plectrum 2a, is " L " type.Be provided with anti-slip veins on described plectrum 2a.
Described catch 2b comprises thin bar 2ba and the inboard thick bar 2bb in the outside, and described thin bar 2ba and thick bar 2bb are one-body molded, and described thin bar 2ba width is narrower than thick bar 2bb, and described catch 2b and movable shield 6 contact-making surfaces are " L " type.During locking movable shield 6, thin bar 2ba contacts with movable shield 6 is positive, and catch 2b is stressed, and suffered moment of torsion outside-in increases, and when thick bar 2bb width is wider than thin bar 2ba, the colleague who saves material, has also guaranteed the torsional property of equipment.The design of " L " type contact-making surface can make catch 2b and movable shield 6 better fit, can be better fixing movable shield 6, prevent the slip that movable shield 6 is horizontal and vertical.Further, described catch 2b and movable shield 6 contact-making surfaces and reverse side thereof all cave inward and are " L " type.Because the moment of torsion that thin bar 2ba is subject to is less, reduce the width of thin bar 2ba, catch 2b still can work, and when having guaranteed security performance, has saved material.And before and after catch 2b, two " L " type designs of both sides, make thin bar 2ba width be narrower than thick bar 2bb, allows thin bar 2ba more easily pass in and out framework 5.
On described holder 1 with sliding seat 2 junctions be provided with fixedly front retaining surface 11 and fixing after shelves face 12, on described sliding seat 2 with holder 1 junction be provided with movable front retaining surface 21 with movable after shelves face 22; During locking, fixedly front retaining surface 11 and movable front retaining surface 21 touch; During release, after fixing rear shelves face 12 and activity, a grade face 22 touches.Described fixedly front retaining surface 11 and fixing after the angle of cut of shelves face 12, than movable front retaining surface 21 with movable after large 8 °-20 ° of the angle of cut of shelves face 22.As preferably, its declinate is 12 °.Declinate is sliding seat 2 activity interval in relative rotation, and when declinate was 12 °, the rotation amplitude of catch 2b was the most suitable.
When not working, described catch 2b stretches into framework 5 and movable shield 6 is stuck under the effect of back-moving spring 4.During work, the operator presses plectrum 2a, and sliding seat 2 turns over certain angle, and after fixing rear shelves face 12 and activity, a grade face 22 touches.Catch 2b turns over certain angle around rotating shaft, and away from movable shield 6, movable shield 6 is able to freely-movable and opens.
After unclamping plectrum 2a, under the effect of back-moving spring 4, sliding seat 2 goes back to certain angle, and fixedly front retaining surface 11 and movable front retaining surface 21 touch, and catch 2b stretches into framework 5 and movable shield 6 is stuck.
The utility model is illustrated according to embodiment, and under the prerequisite that does not break away from the utility model principle, native system can also be made some distortion and improvement.Should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
